Subject [jira] Commented: (MAPREDUCE-768) Configuration information should generate dump in a standard format.

Hemanth Yamijala commented on MAPREDUCE-768:
--------------------------------------------

bq. Because Config can pull in JVM properties, you do need to do the expansion on the host
that is using the configuration.

The current scope of this JIRA is to do the dump on the host that is using the configuration.
Hence, this is covered in HADOOP-6184.

bq. It seems sensible to make this a general purpose Tools option,, print my config to stdout,
so that anyone using any tool can see the values
bq. It's also handy to be able to ask a remote service endpoint for their config -any node,
master or slave, should be able to serve up the config to someone it trusts. Which introduces
one small problem -only users with admin rights should be allowed to see the configurations,
in case they contain passwords or other sensitive topics.

These two are good points and I think we should do them as incremental work. I recommend we
think about it filing another JIRA for the same after this goes in.
